This unit is designed for street rods, pickups, and passenger cars but a BTU rating is not given by the manufacturer. Our customers report satisfactory cooling but use on limos, RV’s, etc. is not recommended.

This A/C unit is only 16” long and 11” deep front to rear and 4.25” tall. Compare those sizes to your available space to determine fit. It could hook up to most compressors and utilizes an expansion valve on the unit. You will still need a receiver/dryer tank with pressure switch but your existing controls could be used if desired.

The under dash A/C will require the condenser, dryer, compressor, hose and fittings, etc. It only consists of the evaporator, duct and blower. It does include an expansion valve.

That AC unit part # 91000535 is 16" long 4.25" tall and 11" deep. You can use those dimensions to check to see if it will fit under the dash of your vehicle. You might want to make a cardboard box that size to mock it up and check for clearance. This AC unit will require a compressor, condenser, filter dryer, and hoses to complete the install

With the multitude of line sizes and fittings I cannot assure you that your lines would be a direct hook up. There is a lot of similarity among the A/C lines and most do run O-ring type seals. Diameter is another question this is where there may be a difference. If there is a difference and you have a hose/machine shop in your area they may be able to replace the existing fittings to match up to the new under dash unit.
